What Is Matter? The New Smart Home Standard Explained

If you've been shopping for smart home devices recently, you may have spotted a new logo appearing on packaging — a simple wordmark that says Matter. It's been showing up on smart bulbs, smart plugs, security cameras, and more across virtually every major brand.

Matter is one of the most significant developments in smart home technology in years. But if you're not sure what it actually means for you as a buyer — or whether it changes what you should be buying right now — this guide explains it clearly and practically.

Matter is a universal smart home standard. In plain terms, it's a shared set of rules that smart home devices use to communicate — a common language agreed upon by every major technology company so that their devices all work together.

Matter is backed by Apple, Google, Amazon, and Samsung, and developed by an industry body called the Connectivity Standards Alliance (CSA). It launched in October 2022 and has been updated regularly since, with Matter 1.5 arriving in November 2025 as the most significant update to date.

The core promise of Matter is simple: if a device carries the Matter logo, it will work with any Matter-compatible platform — whether that's Apple Home, Google Home, Amazon Alexa, or Samsung SmartThings — without needing to check compatibility charts or worry about being locked into one brand's ecosystem.

To understand why Matter matters, it helps to understand the problem it was designed to fix.

Before Matter, the smart home world was fragmented. A smart plug from one brand might only work with Alexa. A smart bulb might need its own dedicated hub. A security camera might require a subscription to a specific cloud service just to function. Zigbee devices needed a Zigbee hub. HomeKit devices might not talk to Google. Z-Wave devices needed yet another bridge.

The result was frustrating for consumers: buying smart home technology meant doing extensive compatibility research before every purchase, and building a mixed-brand smart home was often more complicated than it should have been.

Matter was created to eliminate that fragmentation. One certified standard, covering every major platform, so the question "will this work with my setup?" has a simple answer: if both the device and your platform are Matter-certified, yes.

Matter is an application-layer standard — it defines how smart home devices describe themselves, receive commands, report their status, and authenticate securely with controllers like your phone, voice assistant, or smart speaker.

It runs over three connection types:

• Wi-Fi — the same connection your phone and laptop use. Good for devices that are plugged in and near your router.
• Thread — a low-power mesh network designed specifically for smart home devices. Particularly suited to battery-powered sensors, locks, and buttons. More on this below.
• Ethernet — for wired devices like smart home hubs or panels.

One of Matter's most important features is local control. Unlike many older smart home systems that rely on a cloud server to relay commands — meaning they stop working if your internet goes down or the manufacturer shuts down their service — Matter devices are designed to work directly over your home network. Your automations keep running even during an internet outage.

Matter also allows multi-platform pairing: you can add the same device to Apple Home, Google Home, and Alexa simultaneously, with each platform giving you independent control. Scan the QR code on the device into one app, then scan it again into another. No bridging required.

Thread is a wireless networking protocol — similar to Wi-Fi or Bluetooth, but designed specifically for smart home devices. Matter and Thread are separate technologies, but they work closely together, so it's worth understanding the distinction.

Thread's key advantage is energy efficiency. Because it's a mesh network, Thread devices relay signals between each other — so the more Thread devices you have, the stronger and more reliable your network becomes. This makes it ideal for battery-powered sensors and buttons that need to last months or years without recharging.

To use Thread devices, you need a Thread border router — a device that bridges the Thread mesh network to your home's Wi-Fi and the internet. Several smart home hubs already include one built in: the Apple HomePod mini, Apple TV 4K, Google Nest Hub (2nd gen), and Amazon Echo (4th gen) all act as Thread border routers.

The practical takeaway: if you see "Matter over Thread" on a product box, it means the device uses Thread as its wireless connection and Matter as its communication standard. If you see "Matter over Wi-Fi," it connects to your existing Wi-Fi network instead. Both are fully Matter-compatible — the difference is in how they connect, not whether they work.

All four major smart home platforms now support Matter, though the depth of support varies by device category:

Amazon Alexa — Compatible with Matter via Echo devices (4th gen and later), which include a built-in Thread border router. Alexa's Matter support is strongest for the core categories: plugs, lights, locks, and sensors.

Google Home — Compatible via Google Nest Hub (2nd gen) and other recent Nest devices. Natural fit for Android households and those already using Nest thermostats or Google TV.

Apple Home — Compatible via HomePod mini, HomePod (2nd gen), and Apple TV 4K. Generally regarded as one of the most polished implementations for everyday lighting, locks, and sensor workflows. The Home app on iPhone and iPad provides a clean, integrated interface.

Samsung SmartThings — Often the strongest choice for users who want a broad, cross-brand dashboard that isn't tied to one ecosystem. SmartThings has been consistently quick to implement new Matter versions and was a launch partner for IKEA's Matter-compatible range.

The key thing to check is that your chosen platform supports the device category you want to use — not just Matter in general. Support for foundational categories (plugs, lights, locks, thermostats, sensors) is strong across all four. Newer categories like cameras are still rolling out across platforms in 2026.

Matter launched with a relatively limited set of device categories, but the standard has expanded significantly. In 2026, Matter-certified products cover:

• Smart plugs — control and schedule any plugged-in appliance; many include energy monitoring
• Smart bulbs and lighting — the most mature Matter category, with broad product availability
• Smart locks — keyless entry controllable across platforms
• Sensors — motion, contact, temperature, humidity, and water leak sensors
• Thermostats — compatible smart heating controls
• Window coverings — smart blinds, curtains, and shutters
• Cameras and video doorbells — newly added in Matter 1.5 (see below)
• Energy management devices — smart plugs with detailed energy reporting, EV chargers, and solar inverters

The range of Matter-certified products has grown from a handful at launch to over 750 listed devices, with more being certified regularly as manufacturers adopt the standard.

Matter 1.5, released by the Connectivity Standards Alliance in November 2025, was the biggest update since the standard launched. The headline additions are:

The most-requested addition since Matter launched. Matter 1.5 defines a full camera device type with support for live video streaming, two-way audio, pan/tilt/zoom controls, privacy zones, and both local and cloud recording. This means security cameras can now be controlled from any Matter-compatible platform without being locked to one brand's app. A maintenance update — Matter 1.5.1, released in March 2026 — refined camera support further, improving multi-stream video, HEIC snapshot support, and doorbell chime behaviour.

Matter 1.5 extended energy reporting for smart plugs, EV chargers, and solar inverters. For UK homes on time-of-use energy tariffs — like Octopus Agile — this opens the door to smarter scheduling of high-energy appliances based on when electricity is cheapest.

Garage doors, gates, garden blinds, and window openers now have proper Matter device definitions, bringing outdoor automation into the standard for the first time.

A niche but practical addition for anyone with a garden or greenhouse — soil moisture sensors can now be integrated into a Matter setup alongside other home sensors.

Smart home brand Shelly have embraced Matter, with a wide range of their tech available from Maplin. Here's what that means in practice.

Shelly is a European smart home brand with a particularly strong reputation among home automation enthusiasts — and it has made Matter a central part of its current product generation.

The Shelly Gen4 Series, launched in early 2025, introduced multi-protocol support across Wi-Fi, Bluetooth, Zigbee, and Matter in a single device family. This makes Shelly products unusually flexible: you can connect a Gen4 device to your home using whichever protocol suits your setup, and switch between them as your needs evolve. Matter certification on Gen4 devices enables seamless integration with Apple HomeKit, Google Home, Amazon Alexa, and Samsung SmartThings.

The Shelly Plus Plug UK, available at Maplin, is a strong example of what Shelly brings to the Matter ecosystem. It supports Matter over Wi-Fi, requires no hub, includes precise energy monitoring, and offers advanced automation through scripting capabilities for users who want to go beyond basic scheduling. It supports loads up to 13A — suitable for a wide range of UK appliances.

Beyond smart plugs, Shelly's Matter-compatible range extends across several practical categories:

• Smart switches and relays — including the 1PM Gen4 and 2PM Gen4, which can automate lights, appliances, and motorised blinds or shutters, all with built-in power monitoring
• Outdoor smart plug — the Outdoor Plug S Gen3 brings Matter support and IP44 weatherproofing to garden lighting, patio devices, and outdoor appliances
• Flood sensor — the Flood S Gen4 is Matter-certified and detects water leaks directly at floor level, useful near washing machines, boilers, or under sinks
• Energy meter — the EM Gen4 monitors individual circuits and stores energy data locally, with Matter over Wi-Fi support alongside Zigbee and Bluetooth

One thing worth noting about Shelly's approach to Matter: the brand runs Matter over Wi-Fi rather than Thread, so Shelly devices connect directly to your home router without needing a Thread border router. This keeps setup simple and means Shelly products slot cleanly into virtually any home network without additional hardware.

Shelly is particularly well suited to users who want to go a step further than plug-and-play smart home devices — those who want to automate existing wiring, monitor energy at a circuit level, or build more advanced routines. But the plug-and-play products like the Shelly Plus Plug UK are just as approachable for beginners as any other smart plug on the market.

This is the most practical question most buyers have — and the answer is: no, don't wait.

Here's why:

The devices available today work well. Smart plugs, smart bulbs, and security cameras from established brands including 4lite and Shelly perform reliably right now. The fundamental features — remote control, scheduling, voice assistant integration, energy monitoring — are all fully available.

Many devices already support Matter or have received it via firmware updates. You're unlikely to buy a current smart plug or smart bulb from a mainstream brand and find yourself locked out of Matter compatibility.

The practical rule is straightforward: if the best device for your needs happens to support Matter, great — you're future-proofed. If the best device for your needs doesn't have Matter on the box but works well with your platform of choice, that's still a good buy. Don't let the presence or absence of a logo on the box delay a purchase that would genuinely improve your home today.

The one exception: if you're buying a security camera and want cross-platform flexibility in the future, it's now worth specifically looking for Matter 1.5 compatibility, since camera support is newly standardised and early Matter-compatible camera products are arriving throughout 2026.

Do I need to do anything to use Matter? In most cases, no. If you're buying a new Matter-certified device, you simply pair it with your chosen platform's app (Alexa, Google Home, Apple Home, or SmartThings) using the QR code on the device. The Matter setup process is designed to be simpler and faster than older pairing methods.

Can I use a Matter device with multiple platforms at the same time? Yes — this is one of Matter's most useful features. You can add the same device to Alexa and Apple Home simultaneously, and both will work independently. You don't have to pick one.

Does Matter mean I don't need a hub? For Wi-Fi-based Matter devices, no hub is required — they connect directly to your router. For Thread-based devices, you need a Thread border router, which is built into many modern smart speakers and displays (Echo 4th gen, HomePod mini, Nest Hub 2nd gen). In practice, if you have one of these devices already, you're covered.

Will my existing smart home devices work with Matter? It depends on the device and brand. Some existing devices have received Matter support via firmware updates — WiZ smart bulbs and plugs produced after Q2 2021 are a good example. Others may not be updatable. Check your device brand's support pages or app for Matter compatibility information.

Is Matter the same as Zigbee or Z-Wave? No. Zigbee and Z-Wave are older wireless protocols used by many existing smart home devices. Matter is a newer application standard that runs over Wi-Fi, Thread, or Ethernet. Matter doesn't replace Zigbee or Z-Wave devices — many hubs can bridge existing Zigbee or Z-Wave devices into a Matter network, so you don't necessarily need to replace what you already have.

Is Matter available in the UK? Yes, fully. All four major platforms (Alexa, Google Home, Apple Home, SmartThings) support Matter in the UK, and Matter-certified products are widely available from UK retailers including Maplin.

Does Matter work without the internet? Yes — local control is one of Matter's core design principles. Your automations and in-home control continue to function even if your internet connection goes down. Remote access (controlling devices from outside your home) does require an internet connection, as does voice assistant functionality.

Matter is making smart home technology more open, more reliable, and more future-proof than ever. Whether you're just getting started or looking to expand an existing setup, the products available at Maplin — including the 4lite WiZ Connected smart plugs and smart bulbs, and the Shelly range of Matter-compatible plugs and switches — are compatible with all four major Matter platforms and ready to use today.
